Issue

• After extending a disk on the storage side, the following messages can be seen every time the disk is discovered, i.e., during boot:

Nov  9 11:05:51 rhel72 kernel: sd 9:0:0:3: [sdd] 245760 512-byte logical blocks: (125 MB/120 MiB)

• Why can't I use all the disk space to create a new GPT partition?

Model: Linux device-mapper (multipath) (dm)
Disk /dev/mapper/mpathb: 245760s
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: 

Number  Start  End      Size    File system  Name     Flags
 1      34s    100000s  99967s               primary

(parted) mkpart primary 100001s 245700s                              
Warning: You requested a partition from 100001s to 245700s (sectors 100001..245700).
The closest location we can manage is 100001s to 212958s (sectors 100001..212958).
Is this still acceptable to you?
Yes/No?
